An SEO spam technique meant to railroad search engines into thinking that a web site is
popular by artifically inflating apparent traffic to the site by repeatedly visiting one's own site with a search engine's search bar installed. Generally used by SEO-inept web marketers who are too
lame to legitimately optimize their sites for search engines.
From the
French, claque, meaning, "an organized group of supporters at a theatrical event who try to prompt positive audience response by clapping enthusiastically". Also a play on the traditional American English rendering of the sound made by a
train traveling on a railroad, clickity-clack.
Some SEO spammers are such
duh-weebs that after they get their sites banned from
Google for keyword stuffing, doorway pages, and
link farming, that they think they can still increase their PR, so they download Googlebar and play clickity claque.
